The Aperture Science Hard Light Bridge (also called Hard-Light Surface) is a testing element in Portal 2 that is used throughout the Aperture Science Enrichment Center. Hard Light Bridges are semi-translucent solids made from natural sunlight beamed in from the surface. As its name suggests, it acts as a bridge to the player, usually allowing them to cross Goo to reach inaccessible areas. Bridges can be emitted horizontally or vertically. Horizontal bridges act as a bridge for the player to walk on while vertical bridges act as a shield for the player. (such as blocking Turrets) Just like Excursion Funnels and Thermal Discouragement Beams, Hard Light Bridges can be extended through the use of portals. Although the bridge is made of light, if one portion of the bridge is blocked by a solid object, the rest of the bridge will not continue as a beam of light normally would. Hard Light Bridges can be coated with gels, allowing players to use gels in places where it normally would just fall through. Gels placed on Hard Light Bridges, however, are not permanent and will disappear the moment the bridge dissipitates or moves to a different location.
